Abstract
Even if various types of images exist together in an objective image, it is possible to sufficiently improve the quality of the image at all areas which are to be corrected. An image-correction apparatus has such a structure in which a CPU (10), an image-correction procedure part (12), a color monitor (14), a key board (16), a mouse (18), an inputting device (20), an image memory (22), an image-correction method memory (24), an outputting device (26) and the like are connected to a main bus (50). First, the CPU (10) instructs the inputting device (20) to read the objective image and store resultant data in the image memory (22), and instructs the color monitor (14) to display the objective image, using the image data which are stored. An operator then designate areas to be corrected, and selects a image-correction method which is suitable to the area from four types of image-correction methods, i.e., one for correcting a photograph, one for correcting a black letter against a white background, one for correcting a white letter against a black background and the other for correcting a thin line, while observing the screen display. The image-correction procedure part (12) executes the designated image-correction method on the designated area. The CPU (10) instructs the outputting device (26) to output an image which is expressed by image data which are obtained after execution of the image-correction procedure.
